Welcome to the 2018 catalogue of Groninger - Blaarkop Sires selected by

Cattle Genie Limited from the bull stud of KI-SAMEN. The proofs

displayed are from the April 2018 run.

The Blaarkop breed is the most fertile of all popular dairy breeds

recorded in the Netherlands & the shortest gestation length also. The

breed is often utilised in cross breeding with Friesian dairy herds and the

white marker face and black circles around the eyes is very prolific in

being transferred to offspring, as are the black pigmented hooves and

tongue. Ease of calving is another strong trait no doubt linked to the

much shorter gestation length of the breed.

Groninger -Blaarkop are famed for producing cheeses due to very high

levels of milk Protein and low levels of harmful transient fats.

They are known fondly as the "Polder Panda's" in the Netherlands.

Below is the Dutch base cow table, this is known as "Local" and is set on the MRI breed

evaluation, the Blaarkop, Friesian and breeds such as Fleckvieh are measured on this base.

JULIUS HM is an extremely easy calving Blaarkop bull with a calving survey of 104 and very good calf

survival rates. First calves are born in Dorset have confirmed this and his calves are up and about in no time.

It is a fact that the Groninger Blaarkop breed are recognised for their very short gestation length and in the

case of Julius he has produced UK born calves from HF & Jersey X Bred dairy cows up to 10 days before the

predicted calving date! He is an ideal choice for use in the last week of A.I. in block calving herds & Julius

HM has very fertile semen also.

JULIUS HM ( RF) Grashoek

These calves have all a distinctive facial markings of the Blaarkop enabling them to be identified easily. The

male calves will be highly suited to a grass finishing system, the female calves are ideal for entering the

dairy herd or for a suckler enterprise. These cattle are noted for their hardiness, they have black pigmented

hooves and a winter coat that has a slight curl enabling them to withstand rain and conditions cold better.

High milk protein and good levels of milk fat are traits of the breed and Julius daughters are very good in

this regard, Julius is an A2/A2 bull and is AB Kappa Casein & 110 for daughter fertility and 103 for hoof

health

Groninger Blaarkop bull MATTS is a Willem 5 son and a half brother

to Bertus 12. Willem 5 is a very short gestation bull at -97 and his

daughters are dairy character and have a little hook to the leg.

What is special about MATTS is his dam is also from very short

MATTS

Grashoek

gestation bloodlines, Bayershoeve Piet is -93 for gestation length

and as with Willem 5 he has hundreds of daughters in his proof.

With this pedigree MATTS will provide UK block calving herds with

an ideal bull for end of block use, we are expecting between 7 and

11 days real time reductions in calving dates when used over other

dairy breeds! He has therefore a P.I. of -98 for gestation length

Above & below is pictured dam Mathilde 107 at nine years of age,

she has produced around 4% Milk Protein in her lifetime thus far.

Her dam Mathilde 82 was a lower volume cow who gave very high

milk solids levels. MATTS is suitable for use over maiden heifers.

FERTILITY

Research recently conducted in Holland looked at fertility in lactating dairy cattle and resulted

in presenting a simple table of results for fertility within different breeds.

All breeds have been presented on the Black & White Holstein-Friesian base cow and

therefore positions the B&W Holstein Friesian at 100 which is the breed average.

Below you will find the breed averages listed in order of most fertile first.
